Check the live forecast above for Blacktown, then plan your day around the key takeaway: expect a warm, mostly sunny afternoon with a possible late shower. Western Sydney’s microclimate often runs a few degrees hotter than the coast, so staying sun-smart is wise if you’re heading out.
What’s driving Blacktown’s weather today?
Blacktown sits in Sydney’s western suburbs, where inland heating kicks in quickly under clear skies. The live forecast above shows the temperature climbing through the morning, peaking in the early afternoon. A trough approaching from the west may trigger a brief shower or thunderstorm by late afternoon or evening, but any rain should be light and patchy. Winds will be light and variable, tending north-easterly later — not strong enough to worry about, but enough to shift the humidity.
How does the rest of the week look?
For weather in Blacktown tomorrow, the pattern holds: a warm start, building heat, then another chance of a late storm. The Blacktown weather 10 days outlook suggests a mild end to the week with more settled conditions from Wednesday onwards. If you need a finer view, the Blacktown weather hourly breakdown in the live forecast helps pin down when the best window for outdoor plans is.

Will it rain in Blacktown today?
Based on the live forecast above, there’s a moderate chance of a late shower or thunderstorm, but most of the day stays dry. If you’re gardening or exercising outdoors, plan to finish by early afternoon to be safe.
What’s the best source for Blacktown weather radar?
The Bureau of Meteorology’s Sydney radar (Terrey Hills) covers Blacktown well. For Blacktown weather BOM data, head to their site. The Blacktown weather 30 days outlook is less reliable beyond 10 days, so stick with the 7–14 day range for planning.
How does Blacktown compare to Sydney CBD weather?
Western Sydney is typically 2–5°C warmer in the afternoon than the CBD due to less sea-breeze influence. Overnight lows can also be cooler here in winter. The live forecast above gives you the local picture, while our Sydney weather page covers coastal conditions.
